A mixture of 0.009 mole of triphenylmethyl mercaptan and 0.009 mole of triethylamine in 10 ml. of dimethylformamide is cooled to 0°-5° C. in an ice bath and 0.009 mole of N-acetyl-2-chloroacetamide added. The reaction mixture is stirred at ambient temperature for three hours and then poured into 100 ml. of benzene and 100 ml. of water. The organic layer is separated, washed well with water, dried over sodium sulfate and concentrated to dryness. The residue is crystallized under petroleum ether to give 2.2 g. of Nacetyl-2-(triphenylmethylthio) acetamide.
